I have been the happy owner of an AXE-FX standard for a few years now....I've updated the firmware twice in that period of time, and each time it was a colossal PITA full of trial and error (I'll admit up-front that I am not midi savvy whatsoever). The two previous updates were achieved with the M-Audio UNO interface using Bome's SendSX software. I recently tried updating to v9.0 for several hours and kept getting checksum errors. Since I have read about so many problems with the UNO interface, I upgraded to the MIDISPORT 2x2 Anniversary edition......this hasn't helped at all. I've also tried using MIDI-OX software, and I seem to be getting nowhere fast. Can anyone help this MIDIOT get through this firmware update? I'd be extremely grateful! thanks!
